PCA85232 - NXP

PCA85232 LCD driver

The PCA85232 is a peripheral device which interfaces to almost any Liquid Crystal Display (LCD)1 with low multiplex rates. It generates the drive signals for any static or multiplexed LCD containing up to four backplanes and up to 160 segments. It can easily be cascaded for larger LCD applications. The PCA85232 is compatible with most microcontrollers and co.
